Brassia 'Big Spider'

Brassia Painter ''Big Spider"
Brassia have a very specific method for pollination, it uses entomophily which is pollination by insects and in this case specifically by female spider-hunter wasps of the genera Pepsis and Campsomeris. Mistaken by the mimicry of Brassia, the wasp stings the lip, while trying to grasp its prey without any success. By these movements the wasp comes into contact with the pollinarium, that then sticks to its head. By flying to another Brassia flower, this flower gets pollinated.
